I want to do that and this

Now, I start writing blog in English. Sometimes I think I may write this in Japanese in order to express the plain idea to suit me and what may became idea. At the same time, I want to have a good command of English and read a foreign paper to keep on learning IT over the long time.

In my opinion, writing in English is good effect on talking. Because writing and talking are common in term of an expression. I can reflect mutually.

Well when I can write this speedy, I plan to do both English and Japanese reports. In this case, how can I recognize both? How long can I spend in writing? How do I practice in daily?
